Why do i still have a cold sore close to lip on week after? i even applied abreva and two other cold sore gels everyday.

Treating oral herpes: Docosanol (Abreva) is not effective in speeding healing of oral herpes (cold sore). The only truly effective treatment is valacyclovir (Valtrex) and related drugs. The treatment of choice is a single large dose (2 grams) of valayclovir by mouth as soon as a developing sore is noticed. With other meds or no treatment, typical outbreaks last 10-15 days, so yours should start improving soon.
